ARM: realview: imply device tree boot

Browse Source 
This reduces the Kconfig for the RealView by assuming we are
always booting from the device tree, and removing all the uses
of CONFIG_REALVIEW_DT and replacing with CONFIG_ARCH_REALVIEW.

Further:

- Drop REALVIEW_HIGH_PHYS_OFFSET: we don't use this with device
  tree.

- Drop the REALVIEW_EB_ARM11MP_REVB option: we now handle this
  by simply using another device tree.

- Drop the PB1176 secure flash option: this is defined in the
  PB1176 device tree but marked as "disabled", so users who
  want to use it can simply enable it in the device tree and
  go hacking around.

RealView boards other than PB1176 have the RAM available at
0x70000000, 256MB of which being mirrored at 0x00000000. If
the board supports 512MB of RAM, this option allows the
memory to be accessed contiguously at the high physical
offset. On the PBX board, disabling this option allows 1GB of
RAM to be used with HIGHMEM.
